SEALMASTER RPB series pillow blocks are mounted bearing units designed to support rotating shafts in equipment where a solid base and stable alignment are required. They are used in conveyors, fans, mixers and process machinery. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the right size according to shaft diameter and load type.

The RPB designation is read in parts: the letters identify the pillow block family with mounted bearing, and the numbers that follow indicate the shaft diameter in millimeters. For example, RPB-35MM-2 corresponds to a 35 mm shaft, RPB-50MM-2 to a 50 mm one and RPB-65MM-2 to a 65 mm one. The final suffix distinguishes construction variants within the same size: RPB-60MM-2 and RPB-60MM-4 share the 60 mm diameter but differ in configuration. Send the complete part number to identify the exact variant.

These housings are used in the food, cement, chemical and aggregate processing industries, among others. In Argentina it is common to see them in belt conveyors, bucket elevators, horizontal mixers, centrifugal fans and packaging lines. The pillow block base allows them to be bolted to steel or concrete structures, and the built-in bearing takes radial loads and some axial thrust depending on the mounting. For dusty or humid environments, the choice of sealing is key.

When choosing an RPB housing, verify the shaft diameter, load type and environmental conditions. The sealing must be compatible with dust, water or cleaning agents. Proper lubrication and correct internal clearance extend service life. During mounting, ensure a flat, clean surface, align the housing with the shaft and tighten the mounting bolts evenly to avoid deformation. If the equipment runs with vibration, periodically check the tightness and the condition of the seals.

As for equivalents, SEALMASTER RPB housings can be interchanged with units from other brands that share the same shaft diameter and base configuration, such as the SY, FY or UCP series from recognized manufacturers. Interchangeability depends on the mounting dimensions, center height and shaft locking type. Matching the diameter is not enough: you have to compare hole spacing and load capacity. If you need to replace an existing housing, send us the part number or dimensions and we will tell you the compatible alternative.
